Abstract: The invention relates to a syringe for delivering flowable and/or highly viscous materials with a syringe tube, which has an outlet nozzle, a material container, which is disposed therein, a handle, which is disposed at the end of the syringe tube opposite to the outlet nozzle, and a syringe piston, which can be moved through the handle into the syringe tube. A safe operation is assured, even when larger pressures are exerted, owing to the fact that the handle is connected by means of a thread to the syringe tube and the material container has a closed lateral surface around the axis.
Abstract: Implant (1) for receiving the connecting bridge (17, 17?, 17?) of a medical device, comprising a longitudinal axis (9), a distal end (3) and a proximal end (4), whereby a receiving recess (10) for the connecting bridge (17, 17?, 17?) extends therefrom inside the implant (1), wherein the implant (1) can be connected on its outer surface area to the inner surface area of a receiving bore hole in a bone by force or adaptation, and whereby the connecting bridge (17, 17?, 17?), which is adapted to the receiving recess (10), can be anchored through clamping, shrinkage, adhesion or cementing. The anchored medical device rests on a contact surface (18) of the top (16) protruding radially outward in its cross-section beyond the cross-section of the receiving recess (10) on the proximal end (4) of the implant (1) across the entire surface against an allocated contact surface (5) of the implant (1) on its proximal end (4).
